SOLE-CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 522,799, dated-Tilly10,1894.

Application filed September 5,1893. Serial No. 'l84 836i (No model.)

To ctZZ whom it may concern.-

Be it known that I, JAMEs F. N OONAN, of Lynn, in the county of Essexand State of Massachusetts, have invented certain new and usefulImprovements in Sole-Ohanneling Maghines, of which the following is aspecificaion. i

This invention has for its object to provide an improved machine,primarily for channeling boot and shoe soles, which can be readilyadapted to perform feather edging and other operations.

The invention consists in the several improvementswhich I will nowproceed to describe and claim.

Of the accompanying drawings, forming 'part of this specification:Figure 1 represents a side elevation of a channeling machine embodyingmy improvements. Fig. 2 represents an end elevation of the same. Fig.3'represents a section on line 3-3 of Fig. 1, looking toward the right.Figs. 4 and 5 are elevations of the channel-cutter holder and the Fig. 6represents a secelevations of the slide or block that supports thegroove-cutter. Fig. 9 represents a sectional view'of'a part of achanneled sole.

The same letters of reference indicate the same parts in all thefigures.

In the drawings: a represents the fixed part of the supporting-frame,having bearings for the shaft 1), which carries the work-supporting andfeeding wheel 0.

01 represents the pressure-wheel, which is affixed to the shaft 6, thelatter being journaled in bearings in the movable part a of thesupporting-frame. Said movable part a, which I hereinafter terma head,is pivotally connected at a with the frame a, so that the said head canswing vertically to raise and lower the parts carried by and connectedwith-it.

The head a may be raised by means of a treadle (not shown), a rod fconnected with said treadle, a lever f connected at one end with saidrod and pivoted at f 2 to the frame a, and a rod f bearing on the otherend of the lever f and connected at f with the swinging head a.

Motion may be imparted to the shafts h e by means of a shaft g,journaledin the frame a and having a crank g and a gear 9 a gear g onthe shaft 1) meshing with the gear g and a gear 9 on the shaft 6 meshingwith the gear 9 01' represents a presser-foot, adjustably secured to thehead a and standing beside the wheel (:1, said foot being arranged tobear on the upper side of the sole just in front of the point wherethechannel-cutterand the groovecutter hereinafter described act on thesole. Thefoot d is formed 011 a shank (1 which is vertically adjustableon the head a.

A screw d, the head of which is engaged with a flange on the shank d(see Fig. 3) and l the threaded portion with a threaded socket in thehead a, raises or lowers the shank or foot when rotated.

d represents a clamping-screw, engaged with a threaded socket in thehead a and passing through a slot d in the shank (1 the head of saidscrew being formed to bear on the said shank.

7t represents the channel-cutter, the shank h of which is of dovetailform, and is inserted in a dovetail groove formed in a block or holder2', and maybe secured in said groove by a set-screw h Said holder isformed on a cylindrical stud i, which is embraced by a split clamp j ona dovetail slide j. The clamp is adjusted to grasp or release the studi, by means of a screw f. The slide j is horizontally movable in adovetail guide, formed in a slide or holder 70, which isverticallymovable between guides on the frame a, and is connected bya rod with theswinging head a. so that the cutter rises and falls with the head. Theslide j is adjustable horizontally by means of a screw j the head ofwhich is grooved to engage the edges of aslot a formed in a plate aaffixed to the frame a. The engagement of said head with the slotpermits the screw j to rotate and move up and down, but prevents it frommoving endwise; so that; when the screw is rotated, the engagement ofits threaded portion with a threaded socket in an ear 7' formed on theslide causes the slide to move endwise.

The channel-cutter h is arranged to project into the space between thefeed-wheel and the pressure-wheel, and is enabled by the abovedescribeddevices to be adj usted endwise, sidewise and vertically. An endwiseadjusttoo cutter in a direction at right angles to the shaft 1). Avertical adjustment may be effected by loosening the set-screw k thatsecures the rod k to a socket k formed on the head a, raising orlowering said rod and with it the block In and the channel-cutter, andthen tightening said screw. The cutter may be further adjusted byturning the stud 11' in the socketj, and thus swinging the cutter up ordown and varyingthe angle of its cutting edge.

m represents the groove-cutter, which forms the groove 00 (see Fig. 9)in the channel as made in a sole x by the knife h. Said groovecutter isaffixed to a dovetail holder m, which is fitted to move in a horizontaldovetail groove n in a block or slide it, and is rigidly secured to saidslide by a set-screw n. The slide a is vertically movable between guideson the frame a, and is connected by a rod n with the head a, so that thegroove-cutter, as well as the channel-cutter, moves vertically with thesaid head. The groove-cutter is made adjustable both endwise andvertically by the described devices. An endwise adjustment of saidcutter, in a direction parallel with the shaft 19, may he efiected bymoving the holder m in the slide it; while a vertical adjustment may beeffected by loosening the set-screw n that secures the rod n to a socketn on the head a, and then raising or lowering said rod, the screw beingsubsequently tightened.

It will be seen that both the channel-cutter and the groove-cutter maybe adjusted to suit a considerable variety of requirements, and thateach may be adjusted independently of the other, the channel-cutterhavingalateral movement toward and from the groove-cutter, in additionto the endwise and vertical movements. The slides and it may be movedupwardly, to raise the cutters h and m, by means of screw-rods p g,which are engaged with threaded sockets in the base of the frame a andbear at their upper ends against said blocks, as shown in Figs. 1 and 3.When either rod is rotated to give it an upward movement, the slideagainst which it bears is correspondingly raised- Springs 1" 8,surrounding the rods 19 q, are attached at their lower ends to the framea, and at their upper ends respectively to the slides in n. Said springsexert a downward yielding pull on the slides 70 n, and through saidslides and the rods k n on the head a and its attachments, so that thepresser-wheel d, presserfoot d, channel-cutter h and groove-cutter m areall yieldingly held down by the springs as far as the adjustment of therods p g permits, said rods acting as stops to limit the downwardmovement of the described parts by the springs, and as adjusting devicesto raise the head and its attachments.

if represents a gage-roll,which rotates loosely on a stud affixed to theframe a, and pro ects upwardly from a curved fixed shoulder 16 011 saidframe, said shoulder and gage-roll being at the inner side of thefeed-Wheel. The presser-foot d and wheel at project somewhat below theupper end of the gage-rolLas shown in Fig. 1, and may be adjustedhorizontally toward and from said gage-roll, by means of an adjusting-screw c (Fig. l), the head of which has flanges i) ii engagedwith an ear a on the head a, while the threaded part of said screw isengaged with athreaded socket in the frame a. A slot a receiving thepivot a that connects the head a with the frame a, permits thehorizontal adjustment of the head and of the wheel at and foot 06, whichmay be effected by rotating the screw 7). A slot at in the arm a,permits the required vertical movement of the head a independently ofthe screw '0.

Operation: The sole to be channeled is inserted between the feed-Wheeland presserwheel and foot, the inner edge of the sole bearing againstthe gage-roll t. The wheels 0 d are then rotated, and the sole is thusmoved against the cutters h and m, until a channel of the desired lengthhas been cut, the sole being then removed.

The machine constructed as described may be employed for feather-edgingand other trimming operations, a cutter suited to the desired operationbeing substituted for the channel-cutter, and the groove-cutter removed,if desired.
